BUG: Fixed dirname in a few cases on windows. Now using KWSYS_SHARED_FORWARD_CONFIG_NAME setting instead of CMAKE_INTDIR directly to give choice to user code. Updated documentation to include @KWSYS_NAMESPACE@_SHARED_FORWARD_CONFIG_NAME, @KWSYS_NAMESPACE@_SHARED_FORWARD_OPTION_PRINT, and @KWSYS_NAMESPACE@_SHARED_FORWARD_OPTION_LDD settings.
